Phil,

Return that POS! You won't learn anything about the car with THAT, it is simply a code reader - not worthless but not at all what you want.

HERE is THE tool for under $3000 (no, it's not the $3000 one but c'mon, be reasonable!). This is what the guys who are SERIOUS about working on the car are buying. Yes, there are other items out there, but Cliff in Ohio (badcookie here) swears by this device, and I've read his FB posts about what he has done (mostly for others) with it. You should order one today, it is software upgrade able - that means, when improvements are made, you can download the new firmware and it will have upgrades and fixes they have added after you bought it. If you want to snoop into the car's ECU (and apparently even transmission controller), this is the toy/tool to get. I noticed the garage that put my new tires on has at least one of these in the shop, I asked the guy about it, he said, "I can look like a genius with that thing..."


I still have only my BOSCH 1100, but someday I'm getting a CRP123!!!!!! (I just spent $800 on a convertible top, almost $500 on a new fuel pump and filter/regulator, I am done spending for now.)
